IMPROVEMENT IN CARDlNG-MACHINES.

In the accompanying drawing, Figure 1 rep resents a side elevation of a carding machine. Fig. 2 is a front elevation.

Similar letters of reference indicate corresponding parts.

A is the main carding-cylinder. B represents card-rollers working in connection with the cylinder A, arranged in the ordinary manner. G is what is known as the fancy, and D the dofl'er ofa carding-machine. The doffer is revolved in the usual manner by a belt on the pulley B. The fancy is revolved in contact with the surface of both main cylinderA and the doifer by a belt, F, fromthe main cylinder.

The fancy U is given a traversing or endwisereciprocating motion as it revolves by means of the cam-groove G on the block H of the dofi'er-shaft, as seen in Fig. 2. I is avibrating lever, whose fulcrum is in the bracket J. K is a groove in the ta|icy"-sl1at't. One end of the lever I is in the cam-groove G, and the other in the groove K. 7

It will be seen that, as the doft'ershaft revolves, the" fancy G will be made to traverse back and forth a distance equal to the throw of the cam-groove.

I do not confine myselt'to this particular device, as there are many ways by which this traversing motion could be produced.

The fancy, thus traversing in contact with the surfaces of both the main cylinder and the doiier, keeps the material (wool, &c.,.) on the surfaces of those cylinders more even and uniform than when it is run in the ordinary manner, thereby avoiding streaks of the material on the cylinders.

In ordinary carding-machines the dofi'er requires to be cleaned daily, or at least very frequently; and when low or dirty stoclris used, the doft'er soon becomes coated, so that the stock drops to the floor and becomes waste, thus necessitating cleaning of the doffer several times a day. This of course occasions a stoppage in production, and entails much loss.

My invention, I find from practical experience, renders it unnecessary to remove the dofler for cleaning it for several weeks at a time, as it is cleaned by the teeth of the fancy during the operation of the machine.-

hat I claim is- Thereciprocating fancy -roller 0, arranged to rotate in contact with the dofl'erl) and main cylinder A of a carding-engine, substantially as described, for the purpose specified.
